A Pew survey highlights the pressures that social media, academics and gender norms create for teens.

Research shows that, over the past two decades, rates of mental illness have been increasing in adolescents in many countries. While some scientists point to soaring use of smartphones and social media as a key driver for this trend, others say the evidence does not show a large effect of these technologies on teenagers’ psychological health.

New Pew data shows nearly half of the 1,400 teens surveyed believe social media is harmful to their generation.
